If you’re attempting to ascertain someone’s biological father (or mother) and the presumed parent is unwilling or unable to be tested, you may be able to test grandparents for a likelihood of grandparentage.

Grandparentage testing may also be used to confirm a biological family connection between a young child and extended family provided the legal guardian of the child provides consent for the exam (if they’re a minor).

Just one grandparentage test could be performed if only one grandparent is available for testing. The mother has to be included in this test.

The grandparent DNA testing procedure

We inherit half of our DNA from our biological mothers and the other half from our biological father. Our mothers and fathers obtained their DNA in precisely the same way, so their biological parents will carry the very same genes which trickled down to us. Testing these genes can affirm biological relationships.

All of us obtain a quarter of our genes – 25% – from our grandparents. That’s why, although it’s not quite as powerful as a paternity or maternity test, a grandparent test can still search for DNA matches and offer a probability of biological relationship.

You don’t need to be a local for our team to execute your DNA testing. We can arrange collections across the United States. Once all samples have been collected and sent in, results are available in 5-6 days.

What Needs to be Collected?

To perform Grandparentage Testing, we need to gather samples from:

  • Mother
  • Child
  • Both parents of alleged father

For an examination to be used as defensible evidence for any legal case, proper specimen collection, examination and reporting is required by accredited professionals. Do-it-yourself DNA kits won’t hold up in court since identities are not verified and proper collection procedures aren’t documente

We only use AABB-accredited labs, so we uphold the most detailed standards in DNA laboratory testing.
